Want a safe way to build a habit of saving? A Recurring Deposit (RD) lets you put aside a fixed amount every month and earn guaranteed interest on it. An RD calculator shows you exactly what you’ll have at the end. Let’s walk through it.
What is an RD Calculator?
An RD calculator is a free online tool that tells you the maturity amount and interest earned on a recurring deposit, based on your monthly deposit, interest rate and tenure.
RD stands for Recurring Deposit. Unlike a Fixed Deposit, where you invest one lump sum, an RD lets you deposit a fixed amount every month. The calculator shows your total deposit, the interest earned and the final maturity value.
Quick note: The result is an estimate. Banks may use slightly different rounding or compounding rules, so your actual maturity amount can vary a little.
The RD formula (simple version)
In India, RD interest is usually compounded quarterly. A commonly used formula is:
M = R × [(1 + i)ⁿ − 1] / [1 − (1 + i)^(−1/3)]
| Letter | What it means |
|---|---|
| M | Maturity amount |
| R | Monthly deposit |
| i | Quarterly interest rate (annual rate ÷ 400) |
| n | Number of quarters (months ÷ 3) |
Don’t worry if that looks heavy. The Welytix RD Calculator does it for you in a second.
How to use the RD Calculator
- Enter your monthly deposit, for example ₹5,000.
- Enter the annual interest rate, for example 7%.
- Choose the tenure, for example 5 years.
- See your total deposit, interest earned and maturity amount.
Try different amounts and tenures to find a plan that fits your budget.
Let’s see an example
Say you deposit ₹5,000 per month at 7% interest for 5 years.
| Detail | Amount (approx.) |
|---|---|
| You deposited | ₹3,00,000 |
| Interest earned | ₹59,700 |
| Maturity amount | ₹3,59,700 |
You put in ₹3 lakh and get back about ₹3.6 lakh.
How does tenure change the result?
(₹5,000/month at 7%, compounded quarterly)
| Tenure | You deposited | Approx. maturity amount |
|---|---|---|
| 1 year | ₹60,000 | ₹62,300 |
| 3 years | ₹1,80,000 | ₹2.01 lakh |
| 5 years | ₹3,00,000 | ₹3.60 lakh |
| 10 years | ₹6,00,000 | ₹8.68 lakh |
The longer you stay, the more interest earns interest. Doubling the tenure from 5 to 10 years doubles your deposit, but your interest grows by much more than double.
Why use an RD calculator?
- Know your goal amount: Planning a vacation, a gadget, an emergency fund or school fees? See exactly what you’ll have.
- Compare banks: Enter different interest rates and see which offer pays more.
- No math needed: Skip the formula and the spreadsheet.
- Stay disciplined: Seeing the final number is a good push to keep going.
RD vs SIP: what’s the difference?
| Point | RD | SIP |
|---|---|---|
| Returns | Fixed, known upfront | Market-linked, not guaranteed |
| Risk | Very low | Higher |
| Best for | Short to medium goals, safety | Long-term wealth building |
| Inflation | May not always beat it | Has the potential to, over the long run |
Many people use both: RD for safe, near-term goals and SIP for long-term growth. Compare them with the SIP Calculator.
Common mistakes to avoid
- Missing monthly installments. Banks may charge a penalty for late deposits.
- Breaking the RD early. Premature closure usually means a lower interest rate.
- Ignoring tax. Interest is taxable and banks may deduct TDS above a limit. Check the latest rules.
- Not comparing rates. Even a 0.5% difference adds up over the years.
- Forgetting inflation. Check your real returns with the Inflation Calculator.
